The days of terrible teens ignoring mom and dad's phone calls are no more, with new Android app Ignore No More.

The app enables parents and guardians to lock their child's phone remotely at the click of a button.

Take mom's call or face the consequences ...

Ignore No More has to be installed and set up on the teen's smartphone, and the only way to unlock the phone is by phoning back.

When parents lock the phone from their own device, they are given a password screen and a button to ring to request unlocking — as well as an emergency call option.

And if you think they can uninstall the app, that is also out of the question. Trying to remove Ignore No More also causes the phone to lock and parents have to key in a special code to give them control again and cancel the deinstallation.

The idea was created by Sharon Standifird, a mother from Houston, Texas, who grew tired of her son constantly missing her calls and not calling back.

"I thought it was a good idea, but for other people, not me," she told ABC News.

The app is available in the Google Play store and is due to launch on iPhone in the future.
